2000 Ford F 350 4X4 reverse problem

Also the switch on the side of the transmission (drivers side) surrounding the manual lever tends to want to get contaminated with dirt and water and short out. This causes the gear selection signal being sent to the computer to be in error and consequently incorrect elements are applied causing the lockup you describe. The switch is the easiest to change and costs about $40.

Good luck and hope this helps.

Valve body gasket would blow, or leak between passages due to loose or broken valve body bolts.

Stator support would move where it's pressed into front pump, causing cross-leaks between passages.

Either of the above problems could cause forward and reverse to apply at the same time, binding up the transmission.

The first thing to do on any problem with a puter driven equipment is too reset the puter, Disconnect the battery's (both) over night.

Fords says, passenger negitive first, then driver side negitive.

No, pulling fuse #15 is not the same.

If you still have a problem then it's a valid problem.

My fuel mileage took a dump a couple summers ago and I reset the puter and my mileage came right back. I now reset the puter every two months.

My 15000 mile fuel mileage average with pulling 16k GCW 6000 miles and pulling 28k GCW 450 miles;
